The protocol used is determined by the particular application. Most applications will use TCP or UDP, however you can specify other protocols using the drop-down Protocol menu. Setting the protocol to “all” will cause all incoming connection attempts using all protocols on all port numbers to be forwarded to the specified IP address Advanced Static Routing Dynamic DNS Check Emails Device Management Embedded Web Server SNMP Universal Plug and Play UPnPSNMP V1 and SNMP Version SNMPv2c and SNMPv3 From RFC 1213 MIB-IIFrom RFC1650 EtherLike-MIB From RFC 1493 Bridge MIB From RFC 1472 PPP/Security MIB From RFC 1473 PPP/IP MIBFrom RFC 1474 PPP/Bridge MIB From RFC1573 IfMIB Save Configuration to Flash Logout Chapter 5 Troubleshooting Problems starting up the routerProblems with the WAN Interface Problem Can’t ping any PCs on the LAN Problems with the LAN InterfaceFrequent loss of ADSL linesync disconnections WORLDWIDE APPENDIX A Product Support and Contact InformationContact Billion AUSTRALIA
